Seeing these posts comparing numbers of interviews and the anxiety people feel about their number, I think it's important to remember that different training programs have very different program climates and expectations of students when it comes to this process.
For example, my training program encourages us to apply to ~10 sites and warns us to expect about a 50% hit rate, so they're happy if we get 5 interviews. My best friend's program, however, encourages applicants to apply to at least 20 sites, and she told me that students in her program often feel like failures if they get less than 10-12 interviews due to the pressure their faculty members put on them.
All of our programs have such different experiences and different norms when it comes to APPIC that can leave students feeling uncertain. This site has been really helpful for me in providing information and support throughout this process that I didn't feel like I got from my training program, and I really appreciate everyone's encouragement on here. I hope that we can continue to be empathetic, even if someone's stress is coming from a different place than our own.
